ELECTRICAL SYSTEM
General
The electrical system in your trailer consists of 120-volt AC
(alternating current) and 12-volt DC (direct current) circuits
and components. All installations are made in compliance
with safety requirements of ANSI standard A.1192, National
Electric Code, and Canadian Standards Association.
All trailers will have 30-amp service pre-wired into the breaker box.
Caution: Power surges experienced while plugged in at a campground could
potentially damage electronic component parts in your recreation vehicle. Damage
from power surges are not covered by your Jayco warranty. Consult the component
part manufacturer’s owner’s manual and/or your independent, authorized dealer
for recommendations on power surge protection.
120-Volt AC System
POWER CORD
Your trailer is equipped with a 30-amp rated power cord pre-wired into the breaker box. By
opening the cable hatch door you can pull the power cord out from the compartment and
attach it to the campground power source. Power will enter through the main breaker. It is
distributed through the circuit breakers to wall receptacles and any appliances wired
directly as an air conditioner would be. The cord extends approximately 25’–35’ (7 to 10
meters) from the trailer depending on floor plan. Your RV power cord must be fully
extended and not left coiled in the compartment or on the ground. If the cord is left coiled,
it creates potential for heat to melt the cord’s casing together.
To prevent accidental electrical shock, insure that the ground pin on the attachment plug
cap is intact to the earth ground through the RV park receptacle. Any accidental short of a
live circuit conductor will trip the circuit breaker indicating a shorted circuit. Make sure
that the polarity of the external power is not reversed, in order to avoid harm to appliances
and personal electrical shock. Polarity indicators may be purchased in most electrical and
hardware stores.
It is strongly recommended to avoid the use of extension cords. Using an improper
extension cord will cause overheating of the cord and equipment. It may also cause
premature failure of the AC equipment. If you choose to use an extension cord, it MUST be
the same amperage rating as the RV power cord and be identified for heavy-duty outdoor
use. However, the use of an extension cord can still cause all of the problems discussed
here and will void the warranty.
I
WARNING: Do not use an adapter, cheater or extension cord that will
break the continuity of the grounding circuit connected to the third pin.
NEVER remove the grounding pin to connect a non-grounded, two-prong
receptacle. Any deviation from this will potentially cause a fire from
overheating.
